Hi Carole,

I make it 210 minutes. I also threw away about 2 hours worth of data which I had REALLY mucked up!

Regards,

John

[Can you give me the total imaging time please.]

Great to get first light at long last John, with a full Moon it was a challenge, and has come out fairly well. 

Can you give me the total imaging time please.

Great bunch of images.

AR13827 & AR13825 look exactly the same did you post the right image?

I am  very jealous, as the LRGB Image I believe is the Helping Hand, and one I have had on my list for some time, but never at a dark location when it is high in the sky.  It is on my list for this months DSC.

Your background looks a little bit clipped on my monitor

I always find that I lose quality when I save out from Pixinsight for Astrobin, this is a .png file. Mind you, I probably have subdued the background too much.

Really good John and nicely framed.  Your background looks a little bit clipped on my monitor but it may be me (as in the office, not home).

Astrophotography / C34 HaRGB

Last post by JohnH - Sep 30, 2024, 16:41:35

This is an Ha RGB of The Veil Nebula. The colour data is not as good as I hoped because my guide/tracking settings were not exactly perfect.

Bortle 7 but with a full moon from my observatory ( ) near Bromley South.

Luminance: Ha 45 x 120 sec.
Red: 60 x 40 sec
Green: 60 x 40 sec
Blue: 60 x 40 sec

Telescope: Sharpstar 15028 HNT - focal length 418mm, aperture 150mm and f2.8
Camera: ZWO1600 Pro MM at -10C

ZWO ASIAir mini controlling camera, mount, autofocus, filter wheel and guiding.

Processing: Pixinsight and GraXpert.

Just happy to actually complete an image after so long !!

Regards to all,

John
